PENCIL AND SHARPENER Application filed February 12, 1929. Serial No. 339,303.

This invention relates to new and useful improvements in pencils and has for its object to provide a unique combination of a two in one device, that is of a pencil and a Sharpener, which will have a great scope of usefulness as the sharpening elements, which may be employed in conjunct-ion 'with the actuating means therefor, may be used for a similar purpose in case of cosmetic sticks, crayons and even toothpicks.

The specific construction hereinprovided for will at all times prevent the clogging up of a pencil,as is now the case with the kinds commonly used. At the same time with the self sharpening features employed, a pencil of this sort will always be ready for use and prove a great time-saving device.

It deserves in this connection to be pointed out as a distinct advantage, that the arrangement herein described will prevent any rattling or shaking of the lead when the device is used for the purpose of writing.

The construction is further to the effect that parts of the device may be exchanged and renewed in case of any damage and breakage.

-By a slight modification of the construction space may be provided and arrangement made to receive reserve sticks of lead; in like manner the usual rubber-eraser may be attached to the lower end of the pencil in any convenient manner.

VIt has been an object to make this device strong, durable and easy to operate, and as the construction is comparatively simple the cost of manufacturing should be relatively low.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangements of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming parts of this specication, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a transverse sectional view of my device; Fig. 2 is a sectional view taken on line 2-2 of Fig. 1; Fig. 3 is a central sectional View of the ytop portion; Fig. 4 is a similar view of my device slightly modified; Fig. 5 is a detail view of the clutch member; Fig. 6 is a detail view in section of the clutch member illustrating especially the plunger; Fig. 7 is a detail view of another embodiment of my 55.j device; and Fig, 8 shows a slight modification of the latter in section, while Fig. 9 shows an eraser attachment.

Referring more particularly to the drawings, 10 indicates my device comprising an 60 outer substantially cylindrical memberv or barrel 11, to which is attached, in an integral manner if desired, an inner tube 12 adapted to receivea lead-member 13. The said tube 12 is of a preferably polygonal, in this present 55v instance, hexagonal form, in cross-section, as will be clearly seenin Fig. 2. In fastening the tube 12 to the tubular member 11, it will. be noticed that the said attachment only takes place with reference to the lower sections of 79 the said two members, as indicated, at 14, leaving a cylindrical space 15 between the upper portions of the said two members 11 and 12.

The lower end portion of the said device is closed by a cap-member 16, which may be screwed onto or fastened to the members 11 and 12, or any one of them, as desired, and have provision made for carrying a rubber eraser. Y .y

A clutch-member 17, of a cross-sectional shape substantially as the inner tube member 12, is mounted upon the latter and adapted to slide up and down upon the said tube-member 12 when engaged or acted upon by a top 85- member 18 by means of a screw-threaded engagement. The said member 18 has a reduced cylindrical bottom portion 19 fitted to be mounted within the member 11 in such a Vmanner that the shoulder-portion 20 of the 90 said member 18 ordinarily will rest upon the upper edge of the cylindrical member 11, as indicated at 21.

The said member 18 has its cylindrical bottom portion 19 provided with threads upon its inner side, as at 22 for the purpose of securing a meshing engagement with the clutch member 17 and as the sections effecting the said engagement are Vvery finely threaded a slow motion may be obtained, lo@

suitable to the process ora sharpening the lead of a pencil, this is a feature ot special importance when the means employed to that end are abrasive as, :tor instance, emery, corundum', or a tile member.

rllhe top member 18 has a special conN structed point section 23, which may be rigidly or detachably secured to the said member 18, according to whether provision is made Jfor replacement of the said point section. The member 18 has disposed at its center a tapered bore 24, which is termed according to the means employed tor sharpening the lead; thus the said sharpening process may be effected by forming the bore with screwthreads, as shown in F ig. 3, or grooves, or by arranging a special grinding member within the said bore, the latter member may consist et any hard and suitable material, as corundum, carborundum, emery, etc. The said sharpening may also be accomplished by forming the said conical peint section with an inner bore made as a tile. lt is evident that by turning the top member 18' with its point section 28 the simultaneous cooperation between the section 19 and the clutclimember 17 with its plunger will, as shown, force the lead-stick 18 through the tapered bore 24r-and thereby accomplish the sharpening of the former. lt will be observed that ordinarily the tube member 12 abuts with its upper end against the lower part oi the point section 28 as shown at 27.

The clutch member 17 has disposed a plunger 25 adapted te project into the tube through the longitudinal split 26 iormed in the latter, the said split extending almost to the top edge oit the said tube. ln operating the said device by turningT the top member 18 the lower section 19 thereof will. engage the clutch 17 and urgethe latter upward during which operation a pressure in an upward direction sii ultaneously is exerted upon the lower end ot the lead 13 by the plunger 25 thereby feeding the said lead to the grinding parts of the point section 23, which actually perform the work ot sharpening.

Vhile the arrangements herein described have contempla-ted the use of a lead-stick ot a polygonal shape, a round lead-stick may well be used by employing a special hood member as shown in Fig. 7 and consisting of a somewhat cylindrical barrel formed with a slight outward flaring 32 in an upward direction in order to make the said barrel especially suitable for exerting' a tight grip upon a round lead stick and thereby preventing the latter 'rom turning when being sharpened during the grinding opera-tion.Y As a further means serving the latter purpose the said barrel may be provided with an inner surface having disposed longitudinal grooves 33, as shown in Fig. 8, in order vto secure a still tighter grip upon the Vlead stick.

It is evident that as theV latter form. oi

barrel is engaged by the clutch member, and as the said clutch member advances urging the lead stick forward the latter will be exposed to a tight grip preventing it from turning during operation. ln case any part ci a lead stick shouldever clog up the bore 24, the plunger may readily be used to remove such obstacle. It is desired in this connection to emphasize a modification which may very appropriately be made in regard to the end or" pencil opposite the writing point. Thus, as shown especially in Fig. 9, this arrangement contemplates a cap 16 to which Vis attached the usual rubber' eraser 28, an intermediary tubular member 29 being connected in any suitable manner at one end to the barrel 11 and at the opposite endto the said cap member 16, as illustrated in Fig. 9. The member 29 has inside at its middle disposed a disk 30 in order to prevent the lead sticks from falling out, when the cap 16 is removed and invertedly inserted tor the purpose of using the rubber eraser. By attaching to the said `cap a ring 31, as shown, the pencil may conveniently be connected to a watch chain, thereby securing an easy disengagement between the pencil and the cap and preventingV at all times the loss oi the said cap with the attached rubber eraser.

lt will be evident romthe construction, as herein described, that the pencil point may be withdrawn, when not in use, merely by turning the top member in reversedireetion. It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and l do not therefore limit myself to the Vconstruction and arrangement shown and described herein.
